Title: Casting mold for continuous casting of thin-walled billet
Inventor: TOZAWA KOUICHI
IPC: B22D11/04
Filed: 1984-01-26
Abstract: PURPOSE:To provide a casting mold which yields a thin billet having a good surface condition without buckling a solidified shell by specifying the space between the inside surfaces, in the transverse direction of the billet, of the mold from the position where the solidfied shell is formed to the part for profiling the sectional shape of the intended thin billet and the peripheral length of the inside surface of the mold. CONSTITUTION:The downward drawing mold of, or example, a moving belt type is formed of a pair of short piece parts 1a facing each other and similar long side parts, i.e., moving belts 2a. The position slightly below the top end of the parts 1a is the meniscus part of the molten metal poured into the mold. Said position is substantially the same as the position (designated as A) where the formation of the solidified shell starts. The part near the bottom end of the parts 1a corresponds to the part (designated as B) profiling the sectional shape of the thin walled billet to be obtained finally. The inside surfaces of the molds from the position A to the part B are gradually reduced or expanded in the space between the inside surfaces in the thickness and width direction of the billet toward the drawing direction of the billet. The peripheral length of the inside surface of the mold within the plane intersecting with the billet drawing direction from the position A to the part B is maintained at the size of 0.7- 1.1 times that of the position A as standard.

Title: Double bearing reel
Inventor: NODA HIDEO
IPC: A01K89/0155
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To provide a double bearing reel mounted with a backlash-preventing device capable of affording braking force on a spool through regulating the rotational connection relationship between the spool and a to-be-braked member without the need of disassembling the spool, to-be-braked member and/or braking member and also without the need of high-level processing accuracy. SOLUTION: This double bearing reel has such a scheme that, a conductor 20 is rotatable together with a spool 8 as a unit under pressure contact on the spool 8 by the aid of a changeover member 34; the conductor 20 is subjected to braking force through magnetic flux due to a 1st magnetic body 31 and a 2nd magnetic body 32, thereby the rotation of the spool 8 being in rotation together with the conductor 20 as a unit is braked; when the spool 8 rotates at a low speed, its rotation is intensely braked; in contrast, when the spool 8 rotates at a high speed, its rotation is weakly braked because the spool 8 and the conductor cannot rotate as a unit.

Title: Detection of abnormal photothyristor in converting unit
Inventor: KOBAYASHI ATSUO
IPC: H03K17/73
Filed: 1981-01-30
Abstract: PURPOSE:To detect an abnormally functioning thyristor by a method wherein a forward voltage signal is detected after the passage of a prescribed length of time following the yield of a gate controlling signal. CONSTITUTION:When the normal photosignal (gn) is for some reason (b) or (c) and is received by a thyristor gate, the thyristor voltage (Vtn) is also (b) or (c), reflecting the change. In this case, the forward voltage signal (Fn) outputted by the thyristor is also (b) or (c). The thyristor gate function is checked by the difference between the time point of pulse generator driving signal (PH) input and the time point of signal (Fn) disappearance. That is, after the input of the gate input signal (PH), the forward voltage signals (F1-Fn) at the time point (tdb) of all the serially connected thyristors are memorized and, when all the signals indicate ''0'', there are no abnormalities and, when a signal ''1'' is detected coming out of a thyristor, the thyristor is judged to be in an abnormal state.

Title: Liquid jet recording head
Inventor: SEKIYA TAKURO
IPC: B41J2/05
Filed: 1988-01-22
Abstract: PURPOSE:To obtain excellent discharge performance by determining liquid droplet discharge conditions based on the size of a generated bubble. CONSTITUTION:If the image projection area of a bubble 31 to a thermal energy working part 29 is Sbmum<2> when the bubble 31 becomes largest in size and an energy to be added is E erg in a liquid jet recording head, it must be constituted so that 0.15<=E/Sb<=0.5 is satisfied. The bubble 31 becomes a form close to a cube or a flat form, depending on a method to add a pulse-like energy. In either case, the Sb is defined as the broadcast cross-section when the bubble 31 is cut on the surface parallel to the thermal energy working part 29. Thus conditions for obtaining a stable liquid droplet discharge are determined depending on the size of the generated bubble. Consequently, satisfactory dis charge performance which is not influenced by the physical property of ink, material of a jet recording head, etc., is assured.

Abstract: PURPOSE: To reduce synchronizing capacity of a synchromesh mechanism by constantly connecting a counter gear with a driving shaft.  
     CONSTITUTION: A minor change gear 2 bears a gear 45 with free rotation allowed around an output shaft 11, incorporates a gear 44 on a driving shaft 39, and connects a synchrohub 51 of a synchromesh mechanism 50 to the output shaft 11. Being thus constituted, the gears 44, 45 and a counter gear 46 are always connected and driven on the driving shaft 39 side, and an inertia of the gears 44, 45 and the counter gear 46 does not influence upon a synchronizing capacity of the synchromesh mechanism 50 during a change-over of minor change gear 2. Therefore, the synchronizing capacity of the synchromesh mechanism 50 can be reduced and said mechanism 50 can be miniaturized, and a switching operation can be performed with a little power.

IPC: B60L15/20
Filed: 1992-01-29
Abstract: PURPOSE:To eliminate a time-lag until the start of a motor driver after the issuance of a command by opening a switch, when a current flowing through a filter circuit exceeds a certain level in time case of the operational status of the motor driver other than power running and braking. CONSTITUTION:When a motor driver 24 is in the state of neither power running nor braking, the detected value of a current flowing through the reactor 20a of a filter circuit 20 obtained by a DC voltage detector 28 is outputted as an absolute value from an absolute value circuit 30. The output value and a preset level Iref being the acceptable level of a preset resonance current are compared by a comparator 32 and the comparator 32 outputs a signal when the preset level Iref is exceeded. The output signal of the comparator 32 is applied as open command to a switch 18 to open the switch 18. Therefore, a high resonance current is prevented from flowing and clamped by a charging resistance 22. Accordingly, it is possible to eliminate a time-lag until the start of the driver 24 after the issuance of a power running or braking command.

Abstract: PURPOSE:To obtain the atomic frequency standard unit stable in the frequency at power failure, by applying the control voltage before power failure stored at the voltage storage circuit to the variable capacitor controlling the frequency of the crystal oscillator in the closed loop at the power failure of the main power supply. CONSTITUTION:The frequency of electromagnetic waves from the cell 4 enclosing Rb atoms is modulated with the output of the low frequency oscillator 10, this is discriminated with the phase discriminator 11, and the error signal voltage corresponding to the different frequency from the center frequency is fed to the variable capacitor 16 controlling the oscillation frequency of the crystal oscillator 15 via the voltage storage circuit 32.

The circuit 32 performs A/D conversion 41 for the output voltage of the discriminator 11, stores it in the digital memory 42, and the voltage in D/A conversion 43 is fed to the variable capacitor 16. Although the content of the memory 42 is eventually renewed, the renewal of memory is stopped by the power failure detection circuit 45, the voltage stored immediately before the power failure is fed to the variable capacitor 16, and crystal oscillator is oscillated with the frequency immediately before the power failure.
